THE BASIC PRINCIPLES OF LASER CRYSTAL

Seen strong-point out lasers dependant on laser crystals are compact and light. Lasers from deep purple to blue are reported. Specifically, there were many reports on Pr3+ doped laser crystals, and steady wave lasers all around 490 nm are accomplished. Ti∶sapphire is the main gain crystal for ultrafast lasers. Superintense ultrafast lasers with p
